Systems and methods for providing timely advertising to portable devices

ABSTRACT

Systems and methods for displaying advertisements on a portable device that utilizes an Activity-based operating system are described. The method includes receiving an indication that an Activity is being transitioned away from, and determining whether or not the Activity is finishing. Upon determining that the Activity is finishing, the method includes causing an advertisement display routine to be executed immediately, otherwise submitting the advertisement display routine into a processing queue to be executed subsequently. The advertisement display routine displays the advertisement only upon determining that the state of the Activity and the state of the portable device are characterized by one or more predetermined conditions.

This application claims priority under 35 U.S.C. 119(e) to U.S. provisional application No. 61/646,768 entitled “SYSTEM AND METHOD FOR PROVIDING EVENT-TRIGGERED ADVERTISING TO PORTABLE DEVICES,” filed on May 14, 2012, the content of which is hereby expressly incorporated by reference in its entirety for all purposes.

FIELD

The present disclosure relates generally to timely display of advertising on portable devices based on determining that an Activity component of an application is finishing execution. More particularly, but not exclusively, the present disclosure relates to systems and methods for detecting whether or not an Activity is finishing at a portable device and causing an advertisement display routine to be executed immediately if the Activity is determined to be finishing or otherwise submitting the advertisement display routine into a processing queue to be executed subsequently.

BACKGROUND

Advertising is by its nature disruptive. Very few people will voluntarily choose to be advertised to. People are typically angered by disruption that is caused by receiving pop-up advertisements and the like. Pop-up advertisements are typically delivered using a push model where a server remote from a user device forces advertising on the user device. Typically, the remote server is not aware of activities that the user is involved with on the user device.

Mobile advertising systems have used the push model, whereby some external source sends messages which contain advertising-related information to a handset, and an agent on the handset consumes these messages and renders an advertisement without concern of what the user is doing. For this reason and others, mobile advertising has yet to grow into its full potential.

SUMMARY

Exemplary embodiments of the teachings disclosed herein are shown in the drawings summarized below. These and other embodiments are more fully described in the Detailed Description section. It is to be understood, however, that there is no intention to limit the claims to the forms described in this Summary or in the Detailed Description. One skilled in the art can recognize that there are numerous modifications, equivalents and alternative constructions that fall within the spirit and scope of the disclosed teachings as expressed in the claims.

In one aspect, the disclosure relates to a system and method for displaying advertisements on a portable device that utilizes an Activity-based operating system. The inventive systems and methods include receiving an indication that an Activity is being transitioned away from, and determining whether or not the Activity is finishing. Upon determining that the Activity is finishing, an advertisement display routine is caused to be executed immediately, otherwise the advertisement display routine is submitted into a processing queue to be executed subsequently. The advertisement display routine displays the advertisement only upon determining that the state of the Activity and the state of the portable device are characterized by one or more predetermined conditions.

One aspect in accordance with the disclosure is a method of displaying an advertisement on a display screen of a communication device, where the communication device includes a processor and a memory including program code. The method of this aspect includes receiving an indication of a state transition of a first Activity of an application program being executed on the processor, and executing, by the processor and in response to the indication, the program code in order to determine whether the first Activity is finishing; and display, upon determining the first Activity is finishing, the advertisement upon determining that at least one of the following conditions exists: (a) a second Activity of the application program is not being invoked, (b) the communication device is not involved in a call, (c) the display screen is not locked, and (d) the first Activity is a root Activity or is in a background state.

In another aspect in accordance with the disclosure, a communication device includes a processor, a display screen, and a memory coupled to the processor, the memory containing program code. When executed by the processor, the program code causes the processor to receive an indication of a state transition of a first Activity of an application program being executed on the processor, and execute, in response to the indication, the program code in order to determine whether the first Activity is finishing, and display, upon determining the first Activity is finishing, the advertisement upon determining that at least one of the following conditions exists: (a) a second Activity of the application program is not being invoked, (b) the communication device is not involved in a call, (c) the display screen is not locked, and (d) the first Activity is a root Activity or is in a background state.

In another aspect in accordance with the disclosure, a non-transient computer readable medium stores program code which, when executed by a processor, causes the processor to receive an indication of a state transition of a first Activity of an application program being executed on the processor, and execute, in response to the indication, the program code in order to determine whether the first Activity is finishing; and display, upon determining the first Activity is finishing, the advertisement upon determining that at least one of the following conditions exists: (a) a second Activity of the application program is not being invoked, (b) the communication device is not involved in a call, (c) the display screen is not locked, and (d) the first Activity is a root Activity or is in a background state.

In yet another aspect in accordance with the disclosure, a non-transitory computer readable medium stores computer program code for implementing a method of displaying an advertisement on a communication device. The communication device includes a processor and a user interface. The computer program code includes program code for receiving an indication of a state transition of an Activity of an application program being executed by the processor, program code for determining whether the Activity is finishing, and program code for initiating, based upon the determining, display of the advertisement upon the user interface provided that a state of the Activity and a state of the communication device are characterized by one or more predetermined conditions.

As previously stated, the above-described embodiments and implementations are for illustration purposes only. Numerous other embodiments, implementations, and details of the invention are easily recognized by those of skill in the art from the following descriptions and claims.

DETAILED DESCRIPTION

As discussed above, people are usually annoyed and/or angered by disruption of activity on computers, smart phones, tablets and the like. It has been found that an inverse relationship exists between the extent of an advertisement's disruptiveness and a user's willingness to engage it. Tests of user responsiveness bear this out. These tests have shown that a host system utilizing mobile advertising technology implementing a mechanism whereby mobile advertisements are rendered on behalf of a given application, but outside that application's runtime context are responded to more favorably than other forms of mobile advertising. Systems and methods in accordance with the disclosure identify triggers that ensure that advertising, including rich media advertisements, is rendered when the user completes an activity or otherwise interacts with the system in a way that leaves a window of non-disruptive time. What these triggers are, with what frequency they are leveraged, and which advertising sources to use for content are fully customizable, often from a centralized, cloud-based mechanism (referred to herein as a host system), thereby allowing real-time modification of these parameters across entire user bases.

On the client side, this method of mobile advertising can be accomplished by the presence of an intelligent background agent. In one embodiment, such an agent could comprise a persistent system service which monitors the system for arbitrarily defined triggering events, and takes appropriate action to communicate with advertising providers. The background agent can be configured locally by default configuration parameters and/or remotely by the host system. This is a pull advertising model where the mobile device requests content from the host system, as opposed to a push model where the host system forces content on the mobile device.

It is believed that a person is psychologically more receptive to receiving unexpected content, including advertising content, if the advertising content is displayed in a non-disruptive manner. This approach has been shown by testing to achieve click-through rates (a standard measure of mobile and internet advertising's effectiveness) significantly higher than the industry standard.

In a typical embodiment, a host processing system (also denoted herein as a “host system” for brevity) includes one or more servers (also denoted herein as “host servers” configured to provide access to advertisement information from a myriad of sources, including brick and mortar retailers and wholesalers, online retail website or advertising services, and, in some embodiments, store this information in one or more databases in or associated with the host processing system. The host system may also be configured to interact with the users' portable devices to facilitate transfer of advertisements in a more pleasing fashion.

In addition, the host processing system may be configured to allow the host system or source to configure when information is displayed on a portable device. Portable or mobile devices may be configured in conjunction with a client application to facilitate the display of media content, such as by displaying an advertisement for a device action such as terminating a call.

In an exemplary embodiment, a user is provided with an application program (also denoted herein as a “client application”) that may be installed on the user's portable device to facilitate downloading of media content (e.g., advertisements). The client application can be programmable with various configuration parameters. The configuration parameters can be used to determine which events can cause the client application to request an advertisement for display, how frequently advertisements can be displayed, which activities being performed after the event but prior to display of an advertisement can prevent display of the advertisement, etc.

By way of example, a user may be in the middle of a voice call while the client application is monitoring the operating system. When the voice call is ended, the operating system produces an event signal indicating the call termination event and this signal is detected by the client application. Assuming the client application is programmed to request an advertisement after detecting a call termination event, the client application sends an advertisement request message to a remote system (e.g., an advertisement source system or the host system). The host system, in response to receiving the request message, retrieves a current advertisement from the database and communicates the advertisement to the client application on the portable device. The client application then causes the operating system to display the advertisement on a display of the portable device.

In contrast to the event-based advertising embodiment where advertisements are requested upon an event being detected via a signal from the operating system (as described in reference to FIGS. 4, 5A and 5B below), another embodiment displays advertisements upon determining when an Activity is finishing. As used herein, an Activity is an application component that provides a screen with which users can interact in order to do something, such as dial the phone, take a photo, send an email, or view a map. Each Activity is given a window in which to draw its user interface. One operating system that uses Activities is the Android® operating system. Unlike triggering events, there is no direct indication provided by the operating system that an Activity is finishing. An indirect method of determining when an Activity is finishing is described below in reference to FIGS. 6A, 6B, 6C and 7. This indirect method also utilizes pre-fetching of advertisements since the Android® operating system has built-in delays that make requesting an advertisement after an Activity has finished cumbersome.

The systems and methods disclosed herein are applicable to a wide range of applications related to input, display, storage, processing, transmission, delivery, and other aspects of mobile advertising systems. For purposes of explanation, the following description is provided with reference to specific nomenclature and implementation details, typically in the context of a portable device in the form of a cellular or mobile phone; however, it will be apparent to one skilled in the art that specific details described are not required in order to practice the invention, and that other embodiments in keeping with the spirit and scope of the present invention are possible and fully contemplated herein.

Content Sources and Content Selection and Provision

Attention is now directed to FIG. 1, which illustrates a system 100 on which may be implemented embodiments of the present invention. As shown in FIG. 1, content may originate from sources such as an ABC Manufacturing server 160-1 (i.e., a brick and mortar enterprise), an online retailer server 160-2 (i.e., a server associated with a website) or an advertising service server 160-3, or any of many other sites that contain advertisement information, public service announcements and/or other timely information. In addition to those shown in FIG. 1, it will be apparent to one of ordinary skill in the art that other sources of advertising content are available and other means, in addition to the Internet and Cellular/Telephony networks, may be employed to provide such content. Accordingly, the above list of advertising content sources is only intended to be representative, not limiting.

Communications Between Devices and Systems

System 100 includes one or more portable or mobile devices 110 (also denoted herein for brevity as “devices 110”) such as cellular phones, tablet computers, PDAs, Wi-Fi (802.11) devices or other portable devices. It is further noted that, in some embodiments, the device need not necessarily be portable and the functionality herein may be implemented on more stationary devices such as desktop or notebook computers or other types of fixed devices. In addition, portable devices as described herein may include other types of devices that are mobile but not necessarily portable.

In addition to devices 110, system 100 may include one or more computers 120 such as desktop computers, portable or notebook computers or other devices or systems incorporating computer functionality along with wired or wireless network connectivity. For example, embodiments of the present invention may be implemented on various types of embedded devices or Internet appliance devices or similar types of devices.

System 100 further includes a host processing system 140 (also denoted herein as “host system 140”) comprising one or more servers as well as other associated computer and data processing hardware (not shown in FIG. 1) such as networking equipment, displays, monitors, I/O devices or other computer or data communication systems, hardware and/or software. In an exemplary embodiment, host system 140 may be provided by or operated by an associated host services company or host services supplier.

As noted previously, host system 140 includes one or more servers that include one or more databases 390 (as shown in FIG. 3) either internal or external to the servers 370. These databases may be used to store advertisements and data such as is further described below. Host system 140 may also include one or more operating systems 362 associated with the servers, as well as one or more application programs to implement the various host service functionality as is described further herein. Host system 140 may be implemented at a centralized physical location such as a network connected server farm or other similar facility and/or may comprise a plurality of distributed servers connected by any of a variety of networking connections at different physical locations.

Devices 110 and computers 120 (also denoted collectively herein as devices 110 and 120 for brevity) are typically configured to connect to each other and/or to host system 140 through network 130 as shown in FIG. 1. Network 130 may include wired or wireless networking elements such as Ethernet, LAN technologies, telephony networks such as POTS phone networks, cellular networks, data networks, or other telephony networks as well as Wi-Fi or Wi-Max networks, other wired or wireless Internet network connections and/or other networks as are known or developed in the art. These connections may be facilitated by one or more client applications 264 (as shown in FIG. 2) running on devices 110 or 120 as well as one or more host system applications 364 running on one or more host system servers 370 included in host system 140, along with one more network interfaces 342 and/or other networking hardware and/or software as is known or developed in the art (not shown).

In some embodiments, host system 140 is further configured to provide a network connection through the Internet 150 to one or more advertisement source sites 160, such as the brick and mortar enterprise server 160-1, the online retailer server 160-2, the advertising service server 160-3 or similar sources. These connections may be facilitated by one or more application programs 364 running on host system 140.

As discussed above, a “pull” method, as is known in the art, is used to deliver advertisements to the devices 110 or 120. The devices 110 and 120 can request an advertisement from one or more advertisement source sites 160, such as the brick and mortar enterprise server 160-1, the online retailer server 160-2, the advertising service server 160-3 or similar sources. The network 130 is coupled to the Internet 150 such that the requests can be routed from the devices 110 and 120 to the advertisement source sites 160. In some embodiments, an advertisement is requested by devices 110 or 120 from the host system 140. The advertisements can be requested after a trigger event has been detected. An advertisement is then pulled from either one of the advertisement sources 160 or the host system 140, as determined by configuration parameters as described herein (as used herein, “advertisement source system” refers to either the host system 140 or one of the advertisement sources 160). For example, when device 110 is a cell phone, when the cell phone terminates a call or performs some other trigger event, the client application 264 will create an advertisement request message, which is then sent to an advertisement source. The request message may contain a user identifier, an indication of the type of event, an indication of the type of device, etc. The advertisement source system then retrieves a suitable advertisement from one of several databases. The advertisement source system then sends the selected advertisement to the device 110 or 120 via the network 130. The client application determines if it is still a proper time (as determined by several factors discussed below) to display the advertisement. If it is still a proper time, the client application 264 causes the device 110 or 120 to display the advertisement. The client application 264 may send another message to the advertisement source system indicating whether or not the advertisement was displayed.

Client Application

In one aspect, the user may be provided with a client application or applications 264, as shown in FIG. 2 (also denoted herein as a “client” for purposes of brevity) that may be installed on the user's device 110. For example, the user may be provided with a download of the client application 264 from a host system 140 or affiliated web site. The client application 264 may be installed on a ROM (read only memory) 230 at a factory, thereby negating the need for the user to download the client 264. Alternately, the user may be supplied with the client application 264 on a computer media such as a CD or DVD, a thumb drive, or via other media known or developed in the art. Once the user downloads or otherwise obtains the client application 264 and installs the client application 264 on the user's device 110, the user may then access the host system 140 and associated host service and advertising source systems to implement the functionality described herein. The client application 264 is configured to determine when operating system 262 performs one of the trigger events and then transfers an advertising request message to the advertising source system and receives an advertisement.

For example, in some embodiments, the client application 264 is a game application, a video application or any other type of application that the user would use on the mobile device 110 and the functionality described herein is integrated into the application. In other embodiments, the client application 264 may be utilized by third party application developers and/or advertising services using what is known in the art as a software development kit or SDK. A library of functions of the SDK could be stored in a data module 268 to provide the pull advertising functionality of the client application 264 to a third party applications so as to perform the methods discussed herein. When the client application is part of an SDK (such as with the processes 400 and 500 discussed below) that is a service installed on the portable device 110, an application such as a game that utilizes the client application 264 of the SDK could be installed on the device 110 and the client application 264 would automatically be installed as a separate entity if the client application 264 were not already installed. There could be multiple applications on the device 110 that use the client application 264.

In cases where the client application 264 is part of an SDK on the device 110, upon installation of a new application that utilizes the client application 264, the new application registers with the client application 264. Registration can include the new application providing a unique identifier to the client application 264 such that the client application 264 knows what type of application the new application is. Upon installation of the new application, the client application 264 informs the host system 140 that the new application is installed on the device 110 and is registered with the client application 264.

FIG. 2 illustrates additional details of a typical configuration of a portable device 110 with example device elements that may be used to implement embodiments of the systems and methods in accordance with the disclosure. As shown in FIG. 2, device 110 may include one or more processors (CPUs) 210, which are typically one or more specialized or dedicated portable device microprocessors or microcontrollers, an input/output device module 220 (e.g., a user interface) configured to allow users to input and output information and interact with applications installed on the device 110, such as the client application 264, as well as transfer and receive advertising data, one or more read only memory (ROM) devices 230 or equivalents to provide non-volatile storage of data and/or application or operating system programs, one or more display modules 250, such as an LCD or equivalent display device, as well as one or more memory spaces 260. Other modules, such as optional GPS module 225 for providing position or location information may also be included.

The input/output device module 220, in this example, includes a Home button 222 and a Back button 224. The user can exit an Activity by pressing either the Home button 222 or the Back button 224. The Home button 222 and the Back button 224 can be physical buttons or virtual buttons (e.g., on a touch sensitive display 250). When the user presses the Home button 222, the current Activity is hidden and the display 250 displays a default or Home image. When the Back button 224 is pressed, the current Activity is exited and the display is returned to the display that was being displayed prior to the current Activity.

Memory space 260 may comprise DRAM, SRAM, FLASH, hard disk drives or other memory storage devices configured to store and access operating systems 262, client application programs 264 and/or data 268. Data 268 may include information such as advertisements received from an advertising source system. The advertisements may be in the form of images/photos, videos, music content, or other types of data. In particular, memory space 260 may include one or more client applications 264 stored in the memory space 260 for execution on the CPU 210 to perform the various client-side functionality described herein, including displaying and storing advertisements, or other data or information, as well as interacting with host system 140 and advertising sources 160.

FIG. 3 illustrates additional details of one example of a host system 140 with example device elements that may be used to implement embodiments of the present invention. As shown in FIG. 3, host system 140 may include one or more processors (CPUs) 310, an input/output device module 320 configured to allow users to input and output information and interact with the host system 140 as well as transfer and receive data, one or more read only memory (ROM) devices 330 or equivalents to provide non-volatile storage of data and/or programs, one or more display modules 350 such as a computer monitor or other display device, one or more network connections 340 and associated network interfaces 342 configured to allow host system 140 to connect to other systems, servers and/or portable devices, including other elements of system 140 in embodiments where the servers or other components are distributed at other physical locations, as well as one or more memory spaces 360 and one or more databases 390. Database(s) 390 may be further divided or distributed as one or more sub-databases 390 a-390 n, with the sub-databases storing feature or function specific information associated with a particular feature or function. The various components shown in FIG. 3 may be incorporated in one or more physical servers 370 comprising part of host system 140. It is noted that the various components shown in FIG. 3, including database 390, are typically included as part of server(s) 370, however, they may be external to server(s) 370 in some embodiments. For example, in some embodiments database(s) 390 may be external to server(s) 370 and may comprise part of a separate database server system or networked database system.

Memory space 360 may comprise DRAM, SRAM, FLASH, hard disk drives or other memory storage devices, such as media drives 380, configured to store operating systems, application programs and/or data, and memory space 360 may be shared with, distributed with or overlap with the memory storage capacity of database 390. In some embodiments, memory space 360 may include database 390 or in some embodiments database 390 may include data 368 as shown in memory space 360.

Data stored in memory space 360 and/or database 390 may include information such as advertising source system information, advertisements, images/photos, videos, music content, or other types of data. In particular, memory space 360 may include a host system application or applications 364 stored in the memory space for execution on CPU 310 to perform the various host-side functions described herein.

Host System Server Transmitting Information to Clients

FIG. 4 illustrates an exemplary process 400 for facilitating delivery of information to a portable device in accordance with the disclosure. The process 400 can involve the host system 140 and one or more advertising sources 160 communicating with the portable device 110 via one or more wired and/or wireless communication channels. The process 400 is used with embodiments where client application 264 is part of an SDK that is a service installed on the portable device 110. At stage 410, the host system 140 communicates an advertising application, such as the client application 264 of FIG. 2, to the portable device 110. Alternatively, the client application 264 could be previously stored in a memory of the portable device 110 and stage 410 could be omitted from the process 400.

At stage 414, the host system 140 communicates configuration parameters to the portable device 110. The configuration parameters can be communicated to the portable device 110 in response to receiving a configuration update request from the portable device 110. Such an update request can be made upon first receiving a registration message from the client application 264 with the host system 140 at stage 418, for example. In addition, an update request could be received periodically from the portable device 110 in order to change, for example, which trigger events result in an advertisement being requested by the portable device 110, which advertising source systems to utilize for advertisements and how frequently advertisements can be displayed.

At stage 418, the host system 140 receives a registration message from the client application 264 installed on the portable device 110. The registration message can include information which describes the capabilities of the device 110 as well as other data associated with the portable device 110 and/or the client application 264. For example, one of the portable device 110 capabilities may include display capabilities (number of pixels, video graphics capability, audio capability, etc.) The client application 264 may also tell the host system 140 which event triggers the operating system 262 is capable of reporting to the client application. For instance, trigger events reported by the operating system 262 may include voice call initiation and termination, text message initiation and termination, pausing of a video game application, termination of any type of interactive application, etc.

Additionally, the client 264 may specify picture sizes and formats it wants to receive from the host system 140, such as sizes and formats based on the capabilities of the device 110 and/or based on other parameters such as memory capacity, download connection capacity or costs, or other parameters. The host system 140 receives this information from the client 264, and, in response, in embodiments where the host system delivers advertisements, the host system 140 formats the advertising data specifically for each client based on the client's request and portable device 110 capabilities.

At stage 422, the advertising source system (e.g., either the host system 140 or one of the advertising sources 160 as determined by the configuration parameters) receives an advertisement request message from the client application 264 running on the portable device 110. The advertisement request message may be in response to any of the trigger events that the operating system 262 reports to the client application 264. In addition, the client application 264 can be programmed by the host system 140 via the configuration parameters communicated at stage 414. The advertising request message can include an identifier of the portable device 110 and/or an identity of a user of the portable device 110. The advertising request message can also include an indication of the trigger event that resulted in the request message being communicated.

Upon receiving the advertising request message, the advertising source system determines, at decision block 426, if there are any suitable advertisements to be communicated to the portable device 110. Suitability of the advertisements may be determined based on an identity of the user, a time of day, a geographic location of the portable device, demographics of the user, etc. If no suitable advertisement is identified at the decision block 426, the process 400 returns to stage 422 to receive another advertisement request message.

If a suitable advertisement is identified at the decision block 426, the process 400 continues to stage 430 where the advertising source system selects one of the suitable advertisements and communicates the selected advertisement via the network interface 342 to the portable device 110 to be displayed by the client application 264. The advertisement can be configured based on properties of the portable device 110 such as, for example, display size, video graphics capability, audio capability, etc.

At stage 434, the host system 140 receives an indication, from the portable device 110 via the network interface, of whether or not the advertisement was displayed on the portable device 110. In some cases, the user of the portable device may initiate a new Activity prior to the advertisement being communicated to the portable device 110. In these cases, the client application 264 may determine that it is not a suitable time to display the advertisement because, for example, the advertisement may be a nuisance to the user performing the new Activity. For example, if the user initiates another voice call immediately after terminating one call, this may be determined, based on the configuration parameters, to not be a proper time to display an advertisement. If an advertisement was displayed, the indication received at stage 434 may indicate which advertisement was displayed, which portable device it was displayed on and any user click-throughs or other interaction with the advertisement.

At stage 438, the host system 140 stores an indication in the database 390 of the advertisement that was displayed. In addition, the host system 140 may also store information indicative of user interaction with the advertisement as well as an identity of the user or an identifier of the portable device.

The process 400 is exemplary only and not limiting. The process 400 can be altered, e.g., by having stages added, removed or rearranged. Still other alterations to the process 400 as shown and described are possible.

Receiving Advertisement Information on the Portable Device

FIGS. 5A and 5B illustrate an exemplary process 500 for requesting delivery of information to the portable device 110 in accordance with the disclosure. As with process 400, the process 500 is used with embodiments where the client application 264 is part of an SDK that is a service installed on the portable device 110. After a user has installed the client application 264 on the portable device 110, they can receive advertisement information in a number of ways. Examples are further described below. The process 500 will be described in reference to the portable device 110 (e.g., using the processor 210) and the host system 140, but other devices, portable and non-portable, for example, can be used.

At stage 510, the portable device 110 receives the client application 264 and stores the client application 264 in the memory 260. The client application 264 can be received over a wireless or wired connection via a communications module herein depicted by cellular/network connections 240. For example, a user could download the application from an online applications website, or from one or more third parties that provide applications. Alternatively, the client application can be received in a factory at the time of manufacture/provisioning of the portable device 110 prior to purchase by the user.

Upon completion of the download process, the process 500 continues to stage 514, where an installation process is triggered, during which the client application 264 is installed and registers itself as a system service with the operating system 262 of the portable device 110. A system service is a term of art describing an application that, upon being registered, can run persistently in the background and monitor the operating system 262 for information regarding other events occurring such as the triggering events associated with receiving advertisements. The capabilities of a system service depend on the operating system 262.

In some embodiments, the client application 264 registers with the operating system 262 as a listener for events of interest associated with user interactions with the portable device 110. The events of interest include triggering events indicative of a non-disruptive moment suitable for display of an advertisement (e.g., termination of call, completion of outbound SMS, termination of specific application, etc.). As an example, the operating system 262 may provide a signal indicating that an application identified by a unique identifier has terminated. In cases where applications on the portable device 110 register with the client application 264, the client application 264 uses the registration information to identify exactly which application has terminated. In this way, the advertisements could be targeted to exactly which application has terminated, or paused, etc. In some embodiments, the user of the portable device 110 may be queried for permission to allow the client application 264 to register as a listener for the events of interest. The permission could be an all or nothing permission where the user is asked once for permission for an application to be a listener and no further permission is needed. Alternatively, the query for permission could be done periodically.

The installation of the client application 264 can be triggered by a user initiating the installation by actuating one of the input devices 220 on the portable device. Upon installation and/or activation of the client application, the process 500 continues to stage 518 where the client application 264 determines the update status of the configuration parameters controlling the operation of the client application 264. Upon initial installation and/or activation of the client application, the configuration parameters may be set to default parameter and may not need updating at first. Alternatively, the configuration parameters may not be set at all and may be in need of immediate updating. Configuration parameters can be stored with a date or version number in order for the client application 264 to be able to determine the update status based on a date or version number provided by the host system 140, for example.

At decision block 522, the client application determines if the configuration parameters are current. If the client application 264 has just been installed and the configuration parameters have been set to default values, it may determine at decision block 522 that the configuration parameters are current and not in need of updating. If the client application 264 has been installed with no default configuration parameters, it is determined at decision block 522 that the configuration parameters are not current. In addition, the client application 264 may be configured to update the configuration parameters periodically and it may be determined at decision block 522 that the configuration parameters are not current based on a timer or a version number.

If it is determined at decision block 522 that the configuration parameters are current, the process 500 continues to stage 530. If it is determined that the configuration parameters are not current, the process 500 continues to stage 526 where the client application 264 communicates a request for updated configuration parameters to the operating system 262 which then communicates the request to the host system 140 via one of the network connections 240. In response to the request, the host system 140 sends updated configuration parameters to the portable device 110 which are received by the client application 264 and stored in the memory 260.

The configuration parameters that are received at stage 526 define one or more events that can trigger the client application 264 to request an advertisement from the host system 140. In addition, the configuration parameters can define events that should not be interrupted by displaying an advertisement. The configuration parameters can also be designed to define the frequency that the client application 264 wakes up to perform monitoring of the operating system 262 in order to preserve battery life. Depending on the type of portable device, the configuration parameters could be based on the type of radio connection and further tune the sleep mode/wakeup frequency. The configuration parameters can also include steps used by the client application 264 to remain running at all times, at least in a sleep mode, and steps to enable the client application 264 to restart itself when terminated. Configuration parameters can be customized according to device manufacturer/model, wireless carrier, geographical location, etc. Trigger events defined by the configuration parameters could depend on other equipment connected to the portable device 110. For example, the trigger events could be associated with whether there is a keyboard available or whether there is a Bluetooth headset.

In addition, configuration parameters received at stage 526 can define which advertising source systems the client application should request advertisements from. The configuration parameters could define different advertising source systems depending on, for example, which application the event is associated with, what type of event occurred, the time of day, location, etc.

At stage 530, the client application 264 communicates a registration message to the operating system 262 to be communicated to the host system 140 via one of the network connections 240. The registration message informs the host system 140 that the user has registered the portable device 110 and/or one or more applications to receive advertisements.

At stage 534, upon being activated and registered, the client application 264 begins monitoring the operating system 262 for event signals indicating the occurrences of triggering events that can signal an opportunity to request and display an advertisement. The triggering events can be a termination of a user interaction with the portable device such that the user is not disturbed by an advertisement being displayed. Such triggering events can include call termination, text message termination, application termination or pause, or any other event that signals that the user has completed some form of interaction with the portable device 110. Upon receiving the event signal, the client application 264 reads the event signal to determine what event is indicated to have occurred and queries for the current configuration parameters to determine if conditions are suitable for requesting and displaying an advertisement. In addition to terminating events such as call termination, game termination, text message termination, a trigger event could include non-terminating events such as a lock screen event or a display screen going dark. The client application 264 can be configured such that advertisements that are requested to be displayed during a lock screen or a dark screen even can be persistent and be displayed after the user actuates an input device to unlock or undarken the display screen.

When an event signal is detected at stage 534 by the client application 264, the process 500 continues to decision block 538 where the client application 264 determines if the indicated event is a trigger event, based on the current configuration parameters. If it is determined at decision block 538 that the indicated event is not a trigger event, the process 500 returns to stage 534 where the client application 264 continues to monitor the operating system 262 for event signals. If it is determined at decision block 538 that the indicated event is a trigger event, based on the current configuration parameters, the process continues to stage 542.

At stage 542, the client application 264 communicates an advertisement request message to the operating system 262 to be communicated to an advertising source system, as determined by the configuration parameters, via one of the network connections 240. The advertisement request message can include the trigger event, the identifier of the portable device, the identity of the user, an identifier of the application associated with the event etc. At stage 546, the portable device 110 receives an advertisement selected by the advertising source system. The selected advertisement is received via one of the network connections 240. The advertisement can be received by leveraging webservices over a data (IP) network using HTTP/S encapsulation of SOAP (Simple Object Access Protocol) envelopes containing custom XML payloads optimized for brevity, or via any other available network transport and data description protocols. SOAP is a protocol for exchanging structured information in the implementation of web services.

When an advertisement is being received, in one embodiment, the client application 264 avoids querying the host system 140 for new configuration parameters in order to reduce the amount of network transit, and therefore time required for an advertisement to be displayed. This also reduces the amount of time that the radio is used, thereby saving power because the radio typically uses the most power in the portable device 110.

Upon receiving the selected advertisement, the client application 264 determines, at decision block 550, whether the selected advertisement is suitable for display based on the current configuration parameters. Reasons for an advertisement being unsuitable for display at the time the advertisement is received can include, for example, when the trigger event is closely followed by another event that is determined to be inappropriate to interrupt with an advertisement (e.g., a termination of a text message or call closely following an initiation of another text message or call), a threshold number or count of advertisements having been displayed within a threshold time period being exceeded, a threshold time period has not elapsed since the last advertisement was displayed, a battery power level on the portable device 110 registers below a threshold value, etc. In addition, if no advertisement were available from the advertising source system, there would also be no suitable advertisement for display.

The user could define types of advertisements that should be blocked as being unsuitable. For example, a user could choose to block advertisements for dating websites, alcohol, or other classes of advertisements. These blocked classes of advertisements could be input by the user at stage 518 in the form of configuration parameters.

If it is determined at decision block 550 that the selected advertisement is not suitable for display, the process can return to stage 534 to monitor for more trigger events indicated by event signals or, alternatively, return to stage 542 to request another advertisement. If it is determined that the advertisement is suitable for display, the client application 264 causes the selected advertisement to be rendered on a display of the portable device 110 at stage 554. At stage 558, the client application 264 increments one or more advertisement counters, and in some embodiments stores a time the advertisement was rendered, in order to limit the frequency that future advertisements are displayed. Multiple counters can be used in order to limit the number of advertisements displayed during different time periods such, for example, a number per hour, a number per day, a number per week, etc. At stage 562, the client application 264 causes the operating system 262 to communicate an indication that the selected advertisement was displayed to the host system 140 and/or the advertising source system via one of the network connections 240.

The process 500 repeats to perform the functions of the various stages as discussed above. The process 500 is exemplary only and not limiting. The process 500 can be altered, e.g., by having stages added, removed or rearranged. Still other alterations to the process 500 as shown and described are possible.

In the processes 400 and 500 discussed above, advertisements were displayed on the portable display device upon receiving trigger event signals from the operating system of the portable device 110. However, some operating systems do not provide sufficient signaling for all types of user interaction and trigger events may not provide adequate indications as to when an advertisement should or should not be displayed to a user.

The Android® operating system uses Activities to transition within portions of an application. In contrast to the triggering events discussed above, the Android® operating system does not provide a signal indicating that an Activity is terminating. In contrast, the methods discussed below monitor lower level indicators in order to determine when an Activity is finishing.

As used herein, an Activity is an application component that provides a screen with which users can interact in order to do something, such as dial the phone, take a photo, send an email, or view a map. Each Activity is given a window in which to draw its user interface. The window typically fills the screen, but may be smaller than the screen and float on top of other windows. In contrast to an Activity, a service, as discussed above, is a component that runs in the background to perform long-running operations or to perform work for remote processes. A service does not provide a user interface.

An application usually consists of multiple activities that are loosely bound to each other. One Activity in an application is usually specified as the “main” Activity, which is presented to the user when launching the application for the first time. Each Activity can then start another Activity in order to perform different actions. Each time a new Activity starts, the previous Activity is stopped, but the system preserves the Activity in a processing queue. When a new Activity starts, it is pushed onto the processing queue and takes user focus. The processing queue abides to a basic “last in, first out” queue mechanism, so, when the user is done with the current Activity and presses the Back button, it is popped from the processing queue (and destroyed) and the previous Activity resumes.

FIG. 6A illustrates an exemplary process 600 for displaying an advertisement on the portable device 110 in embodiments that include an Activity-based operating system such as Android®.

Typically, an Activity can be in one of four states:

Foreground—An Activity that is visible in the foreground and is running

Paused—An Activity that has lost focus but is still visible. A paused Activity is alive, but can be killed by the system in low memory situations.

Stopped—An Activity is completely obscured by another Activity and is no longer visible to the user so its window is hidden. A stopped Activity maintains all state information. A stopped Activity can be killed by the system when memory is needed elsewhere.

Dropped—An Activity that was either paused or stopped and was killed by the system. A dropped Activity must be completely restarted in order to be displayed again to the user.

The process 600 is concerned with determining when a Foreground Activity transitions to Paused, Stopped or Dropped states. Activities can transition away from the Foreground state as a result of normal software transitions or because of user interaction. In most cases, transitions from the Foreground state are public events. However, in some instances, an Activity can be transitioned away from due to user interaction and the event is not a public event and is not easily detectable. As discussed above, an Activity can be terminated when the user presses the Home button 222, the Back button 224 or by other means. When a user presses the Home button 222 or the Back button 224, in the Android® operating system, there is not a standard way to know that this press resulted in the user leaving the Activity. The process 600 uses a state-tracking methodology that is able to determine that an Activity is finishing. In addition, the process 600 avoids displaying an advertisement if another Activity is started and the user would be annoyed by an advertisement being displayed.

The Android® operating system presents another challenge to displaying advertisements in a timely fashion. When a user hits the Home button 222 on an Android® device, the Android® operating system forces any new Activities to incur a built-in delay of 5 seconds before the new Activity can be executed. This built-in 5-second delay results in an unacceptable user experience for displaying an advertisement. For this reason, a novel process of displaying an advertisement on a phone that uses the Android® operating system was developed. The process 600 leverages Android® views that are created using the WindowManager class instead of Activities for displaying advertisements. The views created using the WindowManager class are not subject to the built-in 5-second delay when a user presses the Home button 222. The process 600 pre-fetches advertisements in order to display the advertisements in a more timely fashion when it is determined that an Activity is finishing.

When an application that utilizes Activities progresses, an Activity could be transitioned away from for several reasons. An Activity could be caused to be transitioned away from by the user pressing the Home button 222, the user pressing the Back button 224, or the Activity being transitioned away from as part of the normal progression of an application. The process 600 determines when an Activity is finishing as opposed to an Activity merely being transitioned away from and returned to the processing queue.

When a user causes an Activity to finish, or when normal transitions within the application cause an Activity to terminate or be returned to the processing queue, the Android® operating system initiates a termination routine called onPause( ). The call to this onPause( ) routine can be used as an indicator that an Activity is being transitioned away from. The onPause( ) routine is used by software developers to deal with steps needed when a user is leaving an Activity or an Activity is at least leaving visibility. The onPause( ) routine can be modified by software developers to perform different functions when Activities are terminating. This modification is referred to as overriding the onPause( ) routine. The process 600 uses an overridden onPause( ) routine to initiate the advertising logic that determines whether it is a proper time to display the advertisement without annoying the user. Other Activity termination indicators, besides the calling of the onPause( ) routine, can be used in the process 600. The process 600 is described as being performed by a client application, e.g., the client application 264 discussed above.

At stage 605, the client application 264 receives an indication of a state transition of an Activity of an application program being executed. The indication can be the initiation of the overridden onPause( ) routine which is invoked when an Activity is being transitioned away from and leaving visibility on the display 250. The transitioning away from the Activity could be caused by the user of the portable device 110 pressing the Home button 222 or the Back button 224 or by a software transition within the operating application. In the Android® operating system, any event causing an Activity to leave visibility is accompanied by a call to the onPause( ) routine.

At stage 610, the client application 264 invokes an advertising control logic routine in response to receiving the indication of the Activity being transitioned away from. In the case of the Android® operating system, the overridden onPause( ) method is automatically invoked when an Activity is being transitioned away from. The cause of Activity transition can be actions taken by the user or normal transitions within the application that is being executed.

One cause of Activity transition that can take place at stage 605 is the press of the Home button 222 in the Android® operating system. The Android® operating system does not generate a public event when the Home button 222 is pressed. Another cause of Activity transition in the Android® operating system is the press of the Back button 224. The pressing of the Back button 224 is accompanied by an event signal, but the Back button 224 event can be a misleading indicator that the Activity of an application is finishing. For example, a user may press the Back button 224 many times within the normal sequence of an application without causing the Activity, and hence the application, to finish. Due to these subtleties, the handling of Tasks and Activities is of central importance to the proper functioning of the process 600. In order to be certain that the Activity of an application is finishing (exiting the application) upon the pressing of the Home button 222, the Back button 224 or transitioning to another Activity within the Task, the overridden onPause( ) method includes a call to a function within the advertising SDK that invokes the advertising control logic that is performed in stages 615, 620 and 625.

At decision block 615, the client application 264 determines if the Activity is finishing by invoking a routine named isFinishing( ). The isFinishing( ) routine interrogates an ActivityManager class (referred to herein as the ActivityManager) of the operating system to determine if the Activity is finishing or running in the background. If the onPause( ) method was invoked as a result of the user pressing the Back button 224, or due to a transition to another software routine, the Activity will be determined to be finishing. If, at decision block 615, the client application 264 determines that the Activity is finishing, the client application 264 causes a first advertising routine to be executed at stage 620.

In contrast to the pressing of the Back button 224 or a software transition, the pressing of the Home button 222 does not cause an Activity to terminate, but instead puts the Activity in an idle state or running in background. Therefore, if the onPause( ) routine (or other indication of a terminating Activity) was caused to be invoked by the pressing of the Home button 222, the isFinishing( ) routine will determine, at decision block 615, that the Activity is not finishing. If the client application 264 (via the isFinishing( ) method) determines that the Activity is not finishing at stage 615, the client application 264 submits a second advertising routine into the processing queue of the operating system at stage 625. The second advertising routine will be executed subsequently when it reaches the top of the processing queue.

The functions performed at stages 620 and 625 will now be described in reference to FIGS. 6B and 6C. In reference to FIG. 6B, the first advertising routine 620 includes the stages shown. At stage 630, the client application 264 determines if a phone of the portable device 110 is in use, e.g., due to a voice call, a video call, etc. being in progress. If the phone is determined to be in use, the first advertising routine 620 is ended. If the phone is determined not to be in use, the first advertising routine 620 continues to stage 635.

At stage 635, the client application 264 determines if a new Activity was launched and is waiting for a result. A common example of this would be the launching of a camera application within a Task so as to obtain an image from the camera of the portable device 110. If it is determined at stage 635 that a new Activity was launched, the first advertising routine 620 is ended. If it is determined that a new Activity was not launched, the first advertising routine 620 proceeds to stage 640.

At stage 640, the client application 264 determines if the display 250 of the portable device 110 is locked. If it is determined at stage 635 that the display 250 is locked, the first advertising routine 620 is ended. If it is determined that the display 250 is not locked, the first advertising routine 620 proceeds to stage 645.

At stage 645, the client application 264 determines if the finishing Activity is the root Activity. The client application 264 can do this by interrogating the ActivityManager class to determine the current list of Tasks and Activities. If it is determined at stage 645 that the finishing Activity is not the root Activity, the first advertising routine 620 is ended. If it is determined that the finishing Activity is the root Activity, the first advertising routine 620 proceeds to stage 650 and displays the advertisement on the display 250.

The stages shown in the first advertising routine 620 are exemplary only. In some embodiments, one or more of the stages shown in FIG. 6B can be omitted or rearranged. For example, if the portable device 110 does not have a phone or equivalent, the stage 630 can be omitted. In some embodiments, the first advertising routine 620 can be modified to include any one of the decision blocks 630, 635, 640 and 645, any two of the decision blocks 630, 635, 640 and 645, or any three of the decision blocks 630, 635, 640 and 645.

Referring now to FIG. 6C, the second advertising routine 625 includes the stages shown. As discussed above, the second advertising routine 625 is submitted into the queue of the operating system as a result of the Home button 222 being pressed. At stage 655, the client application 264 determines if a phone of the portable device 110 is in use, e.g., due to a voice call, a video call, etc. being in progress. If the phone is determined to be in use, the second advertising routine 625 is ended. If the phone is determined not to be in use, the second advertising routine 625 continues to stage 660.

At stage 660, the client application 264 determines if a new Activity was launched and is waiting for a result. If it is determined at stage 660 that a new Activity was launched, the second advertising routine 625 is ended. If it is determined that a new Activity was not launched, the second advertising routine 625 proceeds to stage 665.

At stage 665, the client application 264 determines if the display 250 of the portable device 110 is locked. If it is determined at stage 665 that the display 250 is locked, the second advertising routine 625 is ended. If it is determined that the display 250 is not locked, the second advertising routine 625 proceeds to stage 670.

At stage 670, the client application 264 determines if the Activity is in the background (in the Paused or Stopped state). The client application 264 can do this by interrogating the ActivityManager class to determine the current list of Tasks and Activities. If it is determined at stage 670 that the Activity is not in the background, the second advertising routine 625 is ended. If it is determined that the Activity is in the background, the second advertising routine 620 proceeds to stage 675 and displays the advertisement on the display 250.

The stages shown in the second advertising routine 625 are exemplary only. In some embodiments, one or more of the stages shown in FIG. 6B can be omitted or rearranged. In some embodiments, the second advertising routine 625 can be modified to include any one of the decision blocks 630, 635, 640 and 645, any two of the decision blocks 630, 635, 640 and 645, or any three of the decision blocks 630, 635, 640 and 645.

As was discussed above, one impediment to a suitable user experience with the Android® operating system is the 5-second delay that is enforced upon Activity launches after the Home button 222 has been pressed. To work around this, a display technique referred to herein as an “Activity-backed Overlay” was devised. The Activity-backed Overlay leverages the Android® WindowManager class addView( ), removeView( ), and updateViewLayout( ) methods to arbitrarily paint Android® View containers (which can hold images, video, web content, etc.) on the display 250. As opposed to an Activity being a task management facility, the WindowManager class functions are a view management facility. Simultaneous to painting one of these Views, the Activity-backed Overlay technique invokes an Activity behind the View on the z-axis of the display 250.

The “backing” Activity is subject to the standard 5-second delay, but the View is not, this enables the technique to display all content (e.g., advertising text, video, audio, etc.) capable of functioning properly without an Activity in the View. When necessary, focus can switch to the Activity. Furthermore, having this z-axis Activity in place enables the Activity-backed Overlay technique to intercept subsequent presses of the Home button 222 and to monitor for transitions to other Activities or Tasks via the Android® operating system's various navigation mechanisms, thus enabling the Activity-backed Overlay technique to remove the View and Activity from the display. In one embodiment, the painting of the View, and the initiation and termination of the View and the Activity is done using Android® WindowManager class functions. The use of the WindowManager class functions requires manual implementation and control of functions that are provided automatically when using Activities, e.g., functionality pertinent to orientation control, video rendering, etc.

Referring now to FIG. 7, an example process 700 includes the stages shown. The process 700 is an example of the Activity-backed Overlay technique used to display advertisements on the Android® operating system. The process 700 can be used at stages 650 and 675 of the first and second advertising routines 620 and 625, respectively.

The process 700 is invoked when it has been determined using the process 600 discussed above (including the first and second advertising routines 620 and 625) that it is a proper time to display an advertisement. At stage 705, the client application 264 simultaneously (or nearly simultaneously) paints a View on the display 250 and invokes a z-axis Activity behind the View. The addView( ) method of the WindowManager is used to paint the View. The View does not include an Activity so the View is not delayed by the Android® operating system subsequent to a pressing of the Home button 222.

At stage 710, the Android® operating system delays the launching of the z-axis Activity, but the View containing the advertisement is not delayed. At stage 715, the client application 264 monitors for subsequent activations of the Home button 222 and other indications of transitions to other activities. This is accomplished using the ActivityManager class.

At stage 720, the client application determines if the Home button 222 was activated a second time or another transition was detected. This second Home button 222 activation is subsequent to the Home button 222 press that resulted in the second advertising routine 625 being invoked. This is done to ensure that the operating system does not get hung-up in limbo. If a positive detection occurs at stage 720, the process 700 proceeds to stage 725 where the client application removes both the View and the z-axis Activity. This is done because it would be inappropriate to continue to display the advertisement when the user is invoking other Activities or Tasks. If no Home button 222 press or other transition is detected at stage 720, the process 700 loops back to stage 715 where the client application continues to monitor for Home button 222 activation and other transitions.

During the 5 second delay, nothing is monitoring for home button presses. During this delay period, the Home button 222 does not function. The Android® operating system prevents any Activity from being executed during this 5 second delay period. The Back button 224 retains functionality during the 5 second delay period. Activation of the Back button 224 will cause the advertisement to be exited. In some embodiments, the View includes a soft-button and the user can exit the advertisement by pressing the soft button. The Home button 222 will not work until the z-axis Activity launches. After the 5-second delay has expired, the z-axis Activity is launched and the z-axis Activity performs the monitoring at stage 715.

In addition to monitoring for Home button 222 presses and other transitions at stage 715, the z-axis Activity also monitors for user interaction with the View advertisement. If the user interacts with the View (e.g., requests more information, downloads images, videos, etc.), the z-axis Activity detects these interactions and invokes the appropriate routines. The z-axis Activity can be configured to terminate itself and the View after a predetermined period of time.

The process 700 is exemplary only and other process can include more stages, omit stages and perform the stage in different orders.
